A display device includes: a substrate; a first bank on the substrate, at least portions of the first bank being spaced apart from each other; a plurality of first electrodes on the substrate, at least portions of the first electrodes being on portions of the first bank; a second electrode on the substrate, the second electrode being spaced apart from and between adjacent ones of the first electrodes; and a plurality of light emitting elements on the first electrodes and the second electrode.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The display device of claim 1, wherein the first electrodes and the second electrode have the same width measured in one direction.
3. The display device of claim 2, wherein a width of the first contact electrodes is smaller than a width of the second contact electrode.
4. The display device of claim 1, wherein at least a portion of the first contact electrodes overlaps a portion of the first bank in a thickness direction.
5. The display device of claim 1, wherein a length of the light emitting elements is longer than a distance between the first electrodes and the second electrode.
6. The display device of claim 1, further comprising a second bank between the substrate and the second electrode.
7. The display device of claim 6, wherein a height of the second bank is smaller than a height of the first bank.
9. The display device of claim 8, wherein the external electrodes cross the first extension portion of the first bank.
10. The display device of claim 9, wherein the internal electrodes cross the first extension portion of the first bank.
11. The display device of claim 9, wherein the internal electrodes are spaced apart from the first extension portion of the first bank and are in the emission regions.
12. The display device of claim 8, further comprising a plurality of second banks on the substrate and overlapping the internal electrodes.
14. The display device of claim 13, further comprising a second bank between the substrate and the third electrode and extending in the second direction.
